MAXEXPONENT — Maximum exponent of a real kind

MAXEXPONENT(X)

MAXEXPONENT(X) returns the maximum exponent in the model of the type of X.

Parameters:

X – Shall be of type REAL.

Returns:

The return value is of type INTEGER and of the default integer kind.

Standard:

Fortran 90 and later

Class:

Inquiry function

Syntax:

RESULT = MAXEXPONENT(X)

Example:

program exponents
  real(kind=4) :: x
  real(kind=8) :: y

  print *, minexponent(x), maxexponent(x)
  print *, minexponent(y), maxexponent(y)
end program exponents
